Initial analysis

The 2-story multi-family residential building at 3110 23rd Street in the Inner Mission, owned by Curtis and Debra M. Cournale, was constructed in 1880 and contains 4 units plus retail space. The property has undergone several significant improvements over the past two decades, including a substantial reroofing project in 2018 costing $27,000, voluntary accessibility upgrades to the retail space in 2014-2014 (completed at $30,000) including a new ramp and restroom modifications, and extensive electrical system upgrades in 2004 with the installation of a new 200-amp service and three meters. The building has maintained its infrastructure through various plumbing improvements, including gas line installations and testing in 2012, and a commercial bathroom renovation in 2014.

Recent concerns include a hot water system complaint filed in November 2023, though its current status is unclear. The property has experienced some recent urban maintenance issues, particularly in late 2024, with multiple reports of illegal parking and several instances of graffiti on public fixtures. Other documented incidents are primarily related to routine urban issues such as garbage disposal and street maintenance, which have generally been resolved. The fire incident history shows minor events, including cooking-related incidents and smoke removal calls, none of which resulted in civilian injuries. The most recent notable development is an approved installation of wireless equipment for T-Mobile on an existing SFPUC steel light pole adjacent to the property.

Risk rating

How 3110 23Rd St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
